Methods and systems for sharing information between processors

A non-transitory, machine readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which when executed by at least one machine, causes the machine to:

• request, by a processor of a first controller, access to a bus attached to a device from a processor of a second controller, wherein the bus and device are shared by the first and second controllers;
• wait for a positive response from the second controller;
• when the positive response is received, access the bus for less than a first timeout period;
• reset a timer before the timer reaches the first timeout period to extend access to the bus, when access is not complete and a total access time is less than a second timeout period;
• and
• release the bus when access is complete or the second timeout period has been reached.

A system comprising:

• a memory containing machine readable medium comprising machine executable code having stored thereon instructions;
• and
• a processor module coupled to the memory, the processor module associated with a first controller and configured to execute the machine executable code to:
• request access to a bus attached to a device from a processor of a second controller, wherein the bus and device are shared by the first and second controllers;
• wait for a positive response from the second controller;
• when the positive response is received, access the device on the bus for less than a first timeout period;
• reset a timer before the timer reaches the first timeout period to extend access to the bus, when access is not complete and a total access time is less than a second timeout period;
• and
• release the bus when access is complete or the second timeout period has been reached.
